My dog, Sonny, has cancer. At least it looks that way. The docs still need to perform a test on the growth on the inside of his mouth to confirm the diagnosis. The growth is exerting pressure on his left eye, so it has probably spread beyond his mouth. That concerns me because if the growth is now in the inside of his skull, that would be very serious.

He has had growths on the eyelid of his left eye before. They irritate the eye. When they have been on the outside of the eyelid, I scrape them off with a q-tip. He had surgery on this eye a couple of years ago to remove a growth when I could not remove it by myself.

He had an issue with this eye two months ago and it did get better after treatment. I left him with my folks while I was out of town on business, and the eye got worse during that time.

I had intended to take him to his regular vet this week, but I will have to be out of town. So, we went to an emergency clinic today to have it looked at. They gave me some fluids to apply to his eye and some drugs to try to reduce the swelling and help with the pain.

I adopted Sonny from Brittany Rescue twelve years ago. He is my best buddy.

I still remember looking at his picture on the BR website before I met him. He looked very happy. I thought he was covered in mud, but realized later that it was just brown spots on his front paws.

When I went out to adopt him, he knew that if he passed the audition, he would get the gig and get to leave his foster home. He was out in the back yard by himself, while the rest of the dogs looked on jealously from their kennels. He was so happy to be loved. He was two years old then. He had been adopted by a family as a puppy, but they gave him up because he was too energetic for them. If I recall the story correctly, he had been placed in at least one other home and was returned because he was too rambunctious for them.

They told me that he would be very happy when he was tired. I added "and wet" to that guidance, because Sonny was always extremely happy when he was tired and wet. In those days, we would walk for an hour a day, six or seven days a week. I would take him on walks where he could swim. He loved the water and would quite literally drag me down to the waters edge so that he could jump in.

He is a house dog, but acts like a hunting dog when we are outside. He would point bunnies and birds. I had never seen a dog point before. He looked just like the pointing scenes that you see in paintings.

He loved to go camping and hiking throughout the woods in Michigan's forests. And, of course, whenever we got to a lake or a stream or a river he would dive right in. He knew what it meant when I would start packing the camping gear in to the car and would leap in to the front seat in eager anticipation of the long car ride to the adventures to come.

He was very afraid of loud noises, like fireworks or thunder until he got older and deafer. He would curl up at my feet and shiver with fear during thunderstorms.

Sonny loved popcorn and would sit next to me while I watched a movie or a hockey game. I would put a few kernels in my hand and he would eat quite happily eat them.

I'm trying to focus on remembering the wonderful life that Sonny has had with me. I am worried about losing my buddy.

How do we explain this so that the user understands it? Is
this a requirement? How would we do this? No.. Focus on the technology…..let
someone else educate patients.

42 CFR Part 2 requires hiding information and not letting
the user know that something is being masked. This is policy. The technology
will support other policies.

System Requirements

Alignment of data segmentation with the ehr functional
model.

How to identify and annotate protected clinical information.

Expectations

Don’t be perfect. This is a draft.
The IG will reference the Use Case document. It will not include the UC doc.

See the presentation for more details.

Thursday Q1

Interesting dynamic between the technical folks and the
policy wonks.

Reviewing the IG.

“Push” is an unsolicited transaction.

DSUB – Document Subscription

0915

Walter Suarez presented on HITSC and Privacy Metadata
(Pcast)

Tagged data elements (atoms)

HIT Standards Committee Meta data tiger team

Focused on

·Patient Identification

·Provenance

·Privacy

PCAST called for metadata on every element. HITSC narrowed
the focus.

Recommendations:

·

Policy Pointer (url to privacy policy that
governs the tde)

·Content medadata

oDatatype (category from a clinical perspective)

oSensitivity (special handling instructions)

Three components necessary to enforce privacy:

·

Policy

·Metadata about the content

·Metadata about the requestor.

External Policy Registry, but no implementation specifics

“Policy” is both regulatory (42cfr) and specific (patient
does not want data shared with dr. smith)

EU regulation contains “a right to be forgotten” in it. Did
HITSC consider this? Issues with lawsuits (how do I defend a decision based on
data that no longer exists). Record retention requirements (term of employment
plus 30 years).

Proposing to add sensitivity codes

·Substance abuse (eth)

·Reproductive health

·Sexually transmitted disease (HIV)

·Mental Health (PSY)

·Genetic Information

·Violence (SDV)

·Other

ANPRM comments.

Thursday Q2 -- 1055

Disclosed metadata is recursive? No. Create as much metadata as possible.

Use a rules engine to apply the rules on the clinical data
prior to sending the document out.

Thursday Q3 – 1330

Focus on the push transaction and the metadata.

How do you convey multiple policies….repeating structure? There
may be more than one policy applied to this document. This metadata will have
to be added to XD*

Then we go through the xs* transactions…..very similar.

Thursday Q4 1600

Bundle XDS and XUA to retrieve the document and authenticate
who the request is from.

Need to
understand the consent directive ig. Go back and read this on the plane.

Where does segmentation happen?

Realized that CDA does not support confidentiality at the
entry level (in R2). Will limit segmentation to the document and section level.
Plus, there is no reliable way to remove content from the narrative.

Friday Q1 -- 0800

Need to write up a strawman for Donna, Joe and Peter to see
if they are interested in being a pilot. Propose Tulsa and Detroit Beacon as
potential pilots. Need to engage Mirth and Apelon. Possibly IHIE? Not really.
They do not support CDA.

We could do the direct as transport protocol. Generate CCD
from Mirth and send it on.

There are pilots of CCDA in the ToC initiative. Need to look
at who is involved.

How to pilot? XD* and the exchange of CCDA should already
exist. We just need to test the segmentation part of the project.

Need pilots that have different architectures and transport
protocols, as it is very unlikely that any one pilot will have all of them.

We already have the use cases. No need to create new ones. Need
to pick a pilot that meets some use cases, not all of them.

SAMHA Pilot.

VA pilot. Using a standard CDA. Working with Apelon. Using
standard terminology from Apelon and Value sets to look at the documents. Access
control system (ACS). Trying to adapt CCDA to behavioral health. Rules engine
to determine what to suppress. GUI for
42CFR Part 2 and Title 38 Section 7332 consent form (one and only one).

Epic.

Epic has a network of their systems. Care Everywhere. No
central repository. Each Epic system is a trusted entity with the others.
56million patients.

Organizations decide how to handle consent. Either opt-in or
opt-out. No re-disclosure. Patient has to issue consent to each organization.

Withheld information can be in several categories:
Organizations can configure sharing. Some departments can be withheld. Some
types of notes can be withheld. Physician flags the note as “sensitive.”
Patients who opt out.

Friday Q2 – 1030

Mitre and hData

What is hData

Organizing data. Metadata. Pub.sub model for data exchange.
They have their own transport and network api.
